What is the splenorenal ligament?

A double-layered peritoneal fold connecting the spleen to the posterior abdominal wall near the left kidney.

In This Section

1. What is the splenorenal ligament?

A double-layered peritoneal fold connecting the spleen to the posterior abdominal wall near the left kidney.

2. What is another anatomical name for the splenorenal ligament?

The lienorenal ligament.

3. Which two anatomical regions are connected by the splenorenal ligament?

The splenic hilum and posterior abdominal wall over the left kidney.

4. From which embryological structure does the splenorenal ligament develop?

The dorsal mesogastrium.

5. What type of tissue forms the two layers of the splenorenal ligament?

Visceral peritoneum.

6. Which major blood vessels pass through the splenorenal ligament?

The splenic artery and splenic vein.

7. Which part of the pancreas commonly extends into the splenorenal ligament?

The tail of the pancreas.

8. Which artery travels through the splenorenal ligament toward the splenic hilum?

The splenic artery, a branch of the celiac trunk.

9. Where does the splenic vein travel after leaving the splenorenal ligament?

Medially along the posterior surface of the pancreas.

10. Which peritoneal cavity lies anterior to the splenorenal ligament?

The lesser sac, also called the omental bursa.

11. What is the relationship between the splenorenal ligament and the lesser sac?

The ligament contributes to the left boundary of the lesser sac.

12. Which peritoneal ligament connects the spleen to the stomach rather than the posterior abdominal wall?

The gastrosplenic ligament.

13. How do the principal contents of the splenorenal and gastrosplenic ligaments differ?

The splenorenal ligament contains splenic vessels and the pancreatic tail; the gastrosplenic ligament contains gastric vessels.

14. What is the main anatomical role of the splenorenal ligament?

It supports the spleen and provides a pathway for vessels and the pancreatic tail.

15. Which retroperitoneal organ lies immediately deep to the posterior attachment of the splenorenal ligament?

The left kidney.

16. Why is the splenorenal ligament important during splenectomy?

It contains the splenic vessels that must be identified and controlled during splenic removal.

17. Why is the pancreatic tail vulnerable during splenorenal ligament dissection?

It lies close to the splenic vessels and may extend nearly to the splenic hilum.

18. What complication may result from injury to the pancreatic tail during splenectomy?

A pancreatic fistula caused by leakage of pancreatic secretions.

19. Why must the splenic artery and vein be carefully separated during hilar dissection?

Their close association creates a risk of major bleeding from accidental vascular injury.

20. What is a spontaneous splenorenal shunt?

An abnormal collateral venous connection between the splenic and left renal venous systems, often associated with portal hypertension.

21. What is the principal purpose of a surgical distal splenorenal shunt?

To divert splenic venous blood into the left renal vein and decompress gastroesophageal varices.

22. Why is identifying splenorenal ligament anatomy important during spleen-preserving pancreatic surgery?

It helps preserve splenic vessels and minimize injury to the spleen during pancreatic tail dissection.
